BALL-BEARING.

SPECIFICATION forming part of Letters Patent No. 623,954, dated April 25, 1899.

Application filed October 4, 18 98.

To all whom, it ntay concern.-

Be it known that LWILLIAM FRIEND, a citizen of the United States, residing at York, in the county of York and State of Pennsylvania, have invented certain new and useful Improvements in Ball-Bearings; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same,

This invention relates to ball-bearin gs; and it consists in the novel construction and combination of the parts hereinafter fully described and claimed.

In the drawings, Figure 1 is a longitudinal section through the bearing Fig. 2 is a longitudinal section showing a modification of the front cone-box. Fig. 3 is a longitudinal section showing a modification in the bearingcones.

A is the tapering end portion of a vehicleaxle of any approved construction, and a is an enlargement at its larger end.

B is a collar on the axle adjacent to the said enlargement, and b is a screw-threaded projection at the front or smaller end of the part A.

O is a sleeve which is fitted to the part A and the enlargement or, and c is a packingwasher, preferably formed of felt, which is interposed between the larger end of the sleeve 0 and the collar B and which projects beyond the periphery of the said collar. The sleeve C has a screw-threaded portion 0' at its smaller end and an enlargement d at its larger end.

D is the rear inner cone of the bearing, which is secured on the enlargement d in any approved manner. The cone D is preferably fitted tightly to the enlargement, and the en largement is provided with a flange d to prevent the cone from slipping off it; but the cone may be secured in any other approved manner, such as by screwing it onto the enlargement.

E is the oil box or chamber,which encircles the sleeve 0, and F is the rear cone-box at one end of the chamber or box E.

G is the rear outer cone of thebearing,which is arranged in the box F and which bears against its shoulder f.

1-1 is an annular plug which is screwed into the end portion of the box F and which presses Serial No. 692,628. (No model.)

the cone G against the shoulder f, so that the said cone is firmly secured in the box. A recess h is formed in the plug H, and h is a packing-washer, preferably of felt, arranged in the recess h around the collar 13 and between the bottom of the said recess and the packing-washer c. The plug H is also provided with a flange I, which bears against the end of the box F, and 2' is an oil-hole formed through the plug and closed by a screw 2''.

J is the front cone-box, which is screwed on or otherwise firmly secured to the smaller end portion of the oil-box E.

K is the front outer cone of the hearing, which bears against the shoulder j of the box J, and j is a screw-threaded portion inside the box J.

M is the front inner cone of the bearing. This cone is adjustable and is screwed on the screw-threaded portion a of the sleeve 0.

N is a jam-nut which is screwed on the projection 13 of the axle. This nut is provided with a flange n, which bears against the cone M and locks it on the sleeve after its position has been adjusted.

The front inner cone M is provided with a peripheral flange m, and m is a packingwasher, preferably formed of felt,which bears againts the flange m and against the end of the front outer cone K. This washer m prevents any oil from running out while the cone M is being adjusted.

P is a cap which is screwed into the screwthreaded portion j inside the box J. The cap P covers the jam-nut and the end of the axle.

R are balls which run in the ball-races formed between the cones D and G and be-' tween the cones M and K.

The vehicle-wheel has its hub secured upon the boxes E, F, and J in any approved manner, or wire spokes may be secured to the said boxes. All the revoluble parts which are screwed into or onto other parts are provided with means whereby they may be engaged by wrenches for turning them. These means are not shown, as they are those ordinarily used, such as notches or angular portions.

The oil-chamber can be filled with oil without removing the wheel from the axle, and the bearing will run for a long time without any attention. The bearing is dust-proof and waterproof, and the cones and balls which are of hardened metal cannot heat and become soft.

This bearing can be fitted to anyaxle new or old by merely reaming out the sleeve to suit the axle, and the balls cannot become lost when the wheel, together with the sleeve, is removed from the axle.

Should any accident happen to the balls or their races, the cone M can be screwed up so as to lock all the balls, and the nut N can be slackened so as to free the sleeve and permit it to revolve on the end portion A of the axle.

According to one modification of this invention the front cone-box J may be provided with an extension-point band J, as shown in Fig. 2, when required. According to another modification of this invention for use on heavy vehicles each pair of cones may be provided with two or more rows of balls, as shown in Fig. The cones are then made longer, and a collar is arranged between the two rows of balls. This collar fits against one of the cones, and itisnot material whether it fits against the inner or the outer cone.

\Vhat I claim is 1. In aball-bcaring, the combination, with an axle the end portion of which is provided with a collar; of a rear cone-box, an outer cone, an annular screwed plug provided with a recess open at its front end and surrounding the said collar, said plug securing the outer cone in the said box, an inner cone connected with the axle, balls between the said cones, and packing arranged between the inner cone and the said collar and within the said recess around the said collar, substantially as set forth.

2. In a ball-bearing, the combination, with an axle the end portion of which is provided with a collar B and a screw-threaded projection I), and a sleeve 0 fitting the said end portion and provided with screw-threads c at its front end; of rear and front inner cones D and m mounted on the said sleeve, a jam-nut screwed on the projection 19 and locking the cone m which is adjustable on the said screwthreads, an oil-box encircling the sleeve and having cone-boxes F and J at its ends, outer cones G and K in the said cone-boxes, an annular plug I securing the cone G and provided with a recess h open at its front end and surrounding the collar B, packing h a between the collar B and the plug H, cone D and end of sleeve 0; packing m, and means for holding the packing m against the end of the cone K and the periphery of the cone 'm, substantially as set forth.

3. In a ball-bearing, the combination, with an axle the end portion of which is provided with a screw-threaded projection; of a front cone-box, an outer cone arranged in the said box, an inner cone provided with a peripheral flange and adjustable longitudinally of and connected with the axle, a jam-nut for the said inner cone screwed on the said projection, packing between the outer cone and the IVILLIAM FRIEND.
